이액상 시스템에서 토양으로부터 비수용성 액체로의 PAHs의 이동특성

Abstract

The transfer behaviors of three Polyarmatic hydrocarbons (PAHs) from soil to non-aqueous phase liquid (NAPL) were investigated. The three different PAHs were phenanthrene, anthracene, and pyrene. The used NAPLs were silicone oil and paraffine oil. The percentage of the remained PAHs into soil were similar without the relation to kinds of NAPLs. And the transfer of PAHs into NAPLs was fastened until 1 day as the increase of mixing rate but in the case of 450 rpm, the remained PAHs into soil was increased after 1 day because NAPLs was emulsified.
